Description

Technical Field

[0001] This invention relates to the field of mushroom bag conveying, specifically an AGV conveying device for edible mushroom bags. Background Technology

[0002] After the edible mushroom spawn bags are automatically packaged, they need to be transported to the storage location. The current transportation method involves loading the spawn bags into baskets at the end of the spawn bag production line, then transferring the baskets to a conveyor rack, which is manually pushed to the storage location. To improve space utilization, the conveyor rack is generally a multi-layered structure, making manual movement time-consuming and labor-intensive, resulting in low efficiency. The current improved technology uses AGVs to automatically transfer and transport the conveyor racks. However, this method requires modification of the AGV itself, installing lifting components to connect or disconnect from the conveyor rack. This not only requires controlling the movement of the AGV but also controlling the connection or disconnection of the lifting components, making the AGV control program more complex. Long-term operation can easily lead to system failures, and the modification of the AGV requires consideration of different types of conveyor racks, necessitating simultaneous hardware and software system modifications, thus increasing the operating cost of the AGV. Summary of the Invention

[0003] The purpose of this invention is to provide an AGV conveying device for edible fungi spawn bags, which can solve the technical problems of complex and costly modification procedures for AGV vehicle body and conveyor frame, reduce the difficulty and cost of modifying AGV vehicle body, and improve the convenience of AGV vehicle body and conveyor frame cooperation.

[0004] To achieve the above objectives, the present invention employs the following technical solution:

[0005] An AGV conveying device for edible mushroom spawn bags includes a conveyor frame disposed on one side of a discharge roller conveyor and an AGV vehicle body for driving the conveyor frame. The bottom of the conveyor frame is equipped with casters. One side of the discharge roller conveyor is equipped with a loading frame for transferring mushroom spawn bag baskets from the discharge roller conveyor to the conveyor frame. A loading platform is slidably connected vertically to the loading frame, and multiple rollers are rotatably connected to the loading platform. A pusher plate is slidably connected laterally to the loading platform for pushing the mushroom spawn bag baskets onto the conveyor frame. The conveyor frame is equipped with multiple layers of support plates, and the bottom of the conveyor frame is equipped with… The device has multiple turntables and a steering assembly that drives the turntables to rotate. Each turntable has multiple receiving slots. A support rod is rotatably connected to one end of the top of each receiving slot. A torsion spring is provided between the support rod and the receiving slot. The bottom end of the support rod extends obliquely to the outside of the receiving slot under the action of the torsion spring. When the AGV vehicle enters the bottom of the conveyor frame from one side, it contacts the support rod and drives the support rod to rotate and enter the inside of the receiving slot. When the AGV vehicle enters the bottom of the conveyor frame from the other side, it contacts the support rod and drives the support rod to rotate to the outside of the receiving slot, where it becomes vertical and contacts the side wall of the receiving slot.

[0006] Furthermore, the steering assembly includes a steering rod that is slidably connected laterally to the bottom of the conveyor frame, the steering rod being provided with a rack, and the sides of the plurality of turntables being provided with gears that mesh with the rack.

[0007] Furthermore, a steering motor is provided at the bottom of the conveyor frame, a screw is provided on the output shaft of the steering motor, a slider is provided on the steering rod, and the screw passes through the slider and is threadedly connected to it.

[0008] Furthermore, the bottom of the conveyor frame is provided with multiple guide rings, and the steering rod is slidably connected to multiple guide rings at the same time.

[0009] Furthermore, both sides of the conveyor frame are symmetrically rotatably connected with baffles for use with the mushroom bag basket. The side of the conveyor frame is provided with a power component to drive the baffles to rotate. The side wall of the receiving groove is provided with a limit switch electrically connected to the power component. When the support rod rotates to the vertical state, it contacts the limit switch.

[0010] Furthermore, the power assembly includes a first telescopic rod, the limit switch is electrically connected to the first telescopic rod, and the end of the first telescopic rod is provided with a contact wheel, which makes rolling contact with the area on the stop bar located between the end and the rotation position.

[0011] Furthermore, the edge of the conveyor frame and the side of the bearing plate are provided with multiple L-shaped blocks, and the stop bar enters the area between the side of the conveyor frame and the L-shaped blocks after it rotates.

[0012] Furthermore, the loading frame is symmetrically rotatably connected to a drive sprocket and a driven sprocket on both sides, and a drive chain is provided between the drive sprocket and the driven sprocket. Fixed blocks are symmetrically provided on the loading platform, and the fixed blocks are fixed to the drive chain.

[0013] Furthermore, the side of the loading platform is provided with a hidden groove for use with a push plate, and the push plate is provided with guide frames symmetrically. The guide frames pass through the hidden groove and are slidably connected to it. The loading frame is provided with a second telescopic rod, and the guide frame is connected to the movable end of the second telescopic rod.

[0014] Furthermore, the bottom of the conveyor frame is symmetrically provided with side baffles for use with the two sides of the AGV vehicle body, and the side of the loading frame is provided with positioning plates, which are in contact with at least two sides of the conveyor frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The structure of this invention utilizes a loading platform on a loading rack to transfer the mushroom bag baskets from the discharge roller conveyor to the conveyor rack. When the mushroom bag baskets move from the discharge roller conveyor to the rollers of the loading platform, the vertical sliding of the loading platform aligns the loading platform with the bearing plates of different heights on the conveyor rack. At the same time, a pusher plate pushes the mushroom bag baskets to move, so that the mushroom bag baskets on the loading platform are smoothly transferred to the bearing plates of different heights on the conveyor rack, realizing the rapid loading and transfer of mushroom bag baskets and improving the efficiency of edible mushroom bag transportation.

[0017] 2. Multiple turntables are rotatably mounted at the bottom of the conveyor frame, each with multiple receiving slots. A support rod is rotatably connected to the top end of each slot, and a torsion spring connects the support rod to the slot. The bottom end of the support rod extends obliquely outward from the slot under the action of the torsion spring. This allows the AGV to enter the bottom of the conveyor frame from one side, contacting the support rod and driving it to rotate into the slot. Similarly, when the AGV enters from the other side, it contacts the support rod, driving it to rotate to a vertical position outside the slot and contacting the side wall of the slot. This structure ensures that when the AGV enters the bottom of the conveyor frame from one side, it contacts the support rod, driving it to rotate to a vertical position and contact the side wall of the slot. This allows the AGV to move smoothly, propelling the conveyor frame under the connection of the support rod. When the AGV enters from the bottom of the conveyor frame... When blocked, the AGV can enter the bottom of the conveyor frame from the other side. At this time, the AGV will contact the support rod and drive the support rod to rotate and enter the inside of the receiving slot. After the AGV passes the support rod, the support rod will return to its original position and extend to the outside of the receiving slot under the action of the torsion spring. Then the AGV moves in the opposite direction, which can drive the support rod to rotate to a vertical position again. This allows for good connection and cooperation with the conveyor frame in different environments. After the conveyor frame is moved into place, the AGV only needs to move in the opposite direction to automatically detach from the support rod, leaving the conveyor frame alone in the storage position. This makes the connection or separation of the AGV and the conveyor frame more convenient, simplifies the control steps of the AGV, and does not require extensive modification of the AGV's hardware and software. Only the movement of the vehicle needs to be controlled, which greatly reduces the difficulty and cost of modification.

[0018] 3. A steering component is installed at the bottom of the conveyor frame to drive the turntable to rotate. With this structure, after the AGV vehicle has transported the empty conveyor frame to its position and filled it with mushroom bag baskets, and it needs to be transported back to the storage position, the steering component can drive the turntable to rotate 180 degrees, so that the support rod can rotate in the direction of the storage position. This allows the AGV vehicle to drive the filled conveyor frame to move towards the storage position. Alternatively, when it is necessary to transport the conveyor frame out of the storage position, the steering component can also drive the turntable to rotate 180 degrees, so that the support rod can rotate out of the storage position. This allows the AGV vehicle to transport the transported conveyor frame back out in the opposite direction. This makes the transport operation of the conveyor frame more convenient and smooth, and improves the convenience of controlling the transport of the conveyor frame. Attached Figure Description

[0030] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0031] Reference Figure 1 and Figure 2This invention describes an AGV conveying device for edible mushroom spawn bags. The main structure includes a conveyor frame 2 located on one side of a discharge roller conveyor 1 and an AGV body 3 that drives the conveyor frame 2. Multiple rollers are rotatably connected to the discharge roller conveyor 1 via bearings. The spawn bag baskets 5, containing the spawn bags, move on these rotating rollers. The conveyor frame 2 carries and transports the spawn bag baskets 5. The AGV body 3 is an automated guided vehicle (AGV) as described in the prior art, capable of moving to a designated position based on positioning. The bottom of the conveyor frame 2 is equipped with casters 4, which are generally universal wheels with self-locking devices to achieve [the desired effect]. The conveyor frame 2 is stable during storage. This structure allows the conveyor frame 2 to move using multiple casters 4 at its bottom. The AGV body 3 is only used to move the conveyor frame 2 and does not need to bear the weight of all the mushroom bag baskets 5 on the conveyor frame 2, thus reducing the load requirements on the AGV body 3. One side of the discharge roller conveyor 1 is provided with a loading frame 6 for transferring the mushroom bag baskets 5 on the discharge roller conveyor 1 to the conveyor frame 2. The loading frame 6 is a frame structure and is fixed to the ground on one side of the discharge roller conveyor 1 by welding or anchor bolts. It is used to transfer the mushroom bag baskets 5 that slide off the discharge roller conveyor 1 to the conveyor frame 2. On the frame 2, a loading platform 7 is vertically slidably connected to the loading frame 6. Preferably, the loading platform 7 has an L-shaped longitudinal section and is driven to slide up and down using any existing power structure. Multiple rollers 8 are rotatably connected to the horizontal portion of the L-shaped loading platform 7 via bearings. The height of the rollers 8 on the loading platform 7 is not higher than the height of the rollers 8 on the discharge roller conveyor 1, allowing the mushroom bag basket 5 to smoothly move from the discharge roller conveyor 1 onto the rollers 8 on the horizontal portion of the loading platform 7 under the action of inertia. Preferably, a retaining edge is provided on one side of the loading platform 7 to prevent the mushroom bag basket 5 from slipping off the loading platform 7. A pusher plate 9 is laterally slidably connected to push the mushroom bag basket 5 onto the conveyor frame 2. The conveyor frame 2 is fixed with multiple layers of bearing plates 10 by welding or bolts. With this structure, after the mushroom bag basket 5 moves onto the loading platform 7, the loading platform 7 rises to the same height as a certain layer of bearing plate 10 under the action of an existing power structure. Then, the pusher plate 9 moves forward under the action of the existing power structure, pushing the mushroom bag basket 5 on the loading platform 7 onto the bearing plate 10 at the corresponding height of the conveyor frame 2, thereby realizing the smooth transfer of the mushroom bag basket 5. The structure is simple and the transfer of mushroom bags is more efficient and accurate.

[0032] The bottom of the conveyor frame 2 is provided with multiple turntables 11 and a steering assembly for driving the turntables 11 to rotate. The top of the turntables 11 is rotatably connected to the bottom of the conveyor frame 2 via bearings. The turntables 11 have a disc-shaped structure. The steering assembly is used to drive the turntables 11 to rotate. The bottom of the turntables 11 is provided with multiple receiving grooves 12. The receiving grooves 12 are recessed inward from the bottom end of the turntables 11. One end of the top of the receiving groove 12 is rotatably connected to a support rod 13 via a pin or hinge. A torsion spring 14 is provided between the support rod 13 and the receiving groove 12. The bottom end of the support rod 13 extends obliquely out of the receiving groove 12 under the action of the torsion spring 14. This structure ensures that the bottom end of the support rod 13 remains extended out of the receiving groove 12 under the action of the torsion spring 14, facilitating entry and exit. The AGV body 3 below the conveyor frame 2 cooperates with the conveyor frame 2. Multiple support legs are provided at the bottom of the conveyor frame 2, leaving space between the turntable 11 and the ground, allowing the AGV body 3 to enter under the conveyor frame 2. When the AGV body 3 enters the bottom of the conveyor frame 2 from one side, it contacts the support rod 13 and drives the support rod 13 to rotate into the interior of the receiving groove 12. When the AGV body 3 enters the bottom of the conveyor frame 2 from the other side, it contacts the support rod 13 and drives the support rod 13 to rotate to the outside of the receiving groove 12, where it becomes vertical and contacts the side wall of the receiving groove 12. Preferably, the bottom end of the support rod 13 is rotatably connected to a roller via a bearing, and the AGV body 3 rolls in contact with the roller, improving the smoothness of their relative movement. This structure allows the AGV body 3 to... After entering the area below the conveyor frame 2 from one side, the AGV body 3 can contact the support rod 13. As the AGV body 3 continues to move, it drives the support rod 13 to rotate outwards towards the receiving groove 12, stretching the torsion spring 14 until the support rod 13 contacts one side wall of the receiving groove 12 and can no longer rotate. In this way, the AGV body 3 can push the conveyor frame 2 to move under the action of the support rod 13, realizing the transfer and conveying of the conveyor frame 2. After the conveyor frame 2 is delivered to its position, the AGV body 3 only needs to move in the opposite direction to detach from the support rod 13, thus leaving the conveyor frame 2 alone in the storage position. After the AGV body 3 leaves on its own, it can transport other conveyor frames 2, making the connection or separation of the AGV body 3 and the conveyor frame 2 more convenient. After the AGV body 3 separates from the support rod 13, the support rod 13 automatically rotates in the opposite direction toward the receiving groove 12 under the action of the torsion spring 14, thus restoring its tilted state with its bottom end outside the receiving groove 12, preparing for subsequent transfer. When the AGV body 3 enters under the conveyor frame 2 from the other side, it will contact the support rod 13 and drive it to rotate into the interior of the receiving groove 12, compressing the torsion spring 14. After the AGV body 3 passes the support rod 13, the support rod 13 rotates in the opposite direction under the action of the torsion spring 14 until its bottom end extends out of the receiving groove 12. At this time, the AGV body 3 can move in the opposite direction to drive the support rod 13 to rotate toward the outside of the receiving groove 12, thereby achieving connection with the conveyor frame 2. This structure is convenient when one side of the conveyor frame 2 is blocked.The AGV body 3 can enter from the other side of the conveyor frame 2 and then drive the conveyor frame 2 to move, thus enabling the AGV body 3 to meet the connection and cooperation requirements with the conveyor frame 2 under different environmental conditions and improving the flexibility of connection and cooperation with the conveyor frame 2. When the AGV body 3 transports the empty conveyor frame 2 to the discharge roller conveyor 1 for loading, if it is necessary to move the conveyor frame 2 filled with mushroom bag baskets 5 out again, or after transporting the conveyor frame 2 filled with mushroom bag baskets 5 to the storage position, it is necessary to move the conveyor frame 2 out again. At this time, the steering component can be used to drive the turntable 11 to rotate 180 degrees, so that the state of the support rod 13 is reversed. At this time, the AGV body 3 can re-enter under the conveyor frame 2 from the side where it previously exited, until it passes the support rod 13 and then moves in the opposite direction, so that the support rod 13 can be driven to rotate to the outside of the receiving groove 12 and become vertical. Then the AGV body 3 can be used to drive the conveyor frame 2 to move under the conveyor frame 2. With the support rod 13 connecting to the AGV body 3, the conveyor frame 2 is moved out. This allows the AGV body 3 to transport the conveyor frame 2 to its designated position and then move it out again. This avoids the situation where the AGV body 3 cannot easily access the underside of the conveyor frame 2 to connect and cooperate when the side of the conveyor frame 2 is blocked by other conveyor frames 2 or objects. This ensures the convenience of the AGV body 3 in transferring and transporting the conveyor frame 2. This structure does not require extensive modification to the purchased AGV body 3; only a turntable 11 and steering assembly need to be added to the bottom of the conveyor frame 2. It enables accurate cooperation between the AGV body 3 and different types of conveyor frames 2, greatly reducing the difficulty and workload of modification and lowering the cost of use. Furthermore, the AGV body 3 only needs to be controlled to move, greatly simplifying the control steps. Long-term use is less prone to system failure, improving the efficiency and convenience of transporting edible mushroom bags.

[0033] Preferred, refer to Figure 7 The steering assembly includes a steering rod 15 that is laterally slidably connected to the bottom of the conveyor frame 2. The steering rod 15 can be manually driven or driven by a motor or other drive components. A rack 16 is fixed to the steering rod 15 by welding or bolts. The sides of the multiple turntables 11 are all fixed with gears 17 that mesh with the rack 16 by welding or integral molding. With this structure, when the steering rod 15 slides laterally, the multiple turntables 11 can be driven to rotate synchronously by 180 degrees under the meshing action of the gears 17 and the rack 16, so as to realize the rapid adjustment of the state of the turntables 11, simplify the operation steps of the steering assembly, and improve the convenience of changing the state of the turntables 11.

[0034] Preferably, a steering motor 18 is fixed to the bottom of the conveyor frame 2 by welding or bolting. A screw 19 is fixed to the output shaft of the steering motor 18 by welding or bolting. A slider 20 is fixed to the steering rod 15 by welding or integral forming. The screw 19 passes through the slider 20 and is threadedly connected to it. This structure uses the steering motor 18 to drive the screw 19 to rotate, and under the action of the threaded connection, it drives the slider 20 and the steering rod 15 to slide, thereby realizing the rapid sliding drive of the steering rod 15. It does not require manual sliding operation of the steering rod 15, which simplifies the control steps and improves the steering efficiency of the turntable 11.

[0035] Preferred, refer to Figure 4 and Figure 5 The bottom of the conveyor frame 2 is fixed with multiple guide rings 21 by welding or bolts. Preferably, the longitudinal section of the guide ring 21 is C-shaped. The steering rod 15 is slidably connected to multiple guide rings 21. This structure uses multiple guide rings 21 to guide the sliding of the steering rod 15, making the lateral sliding of the steering rod 15 smoother and more stable. The rack 16 is set on the opening side of the C-shape, thereby avoiding motion interference between the rack 16 and the guide rings 21 and ensuring the smoothness of the turning process of the turntable 11.

[0036] Preferably, both sides of the conveyor frame 2 are symmetrically connected by pins or hinges to stop bars 22 for use with the mushroom bag basket 5. Preferably, a return spring is provided between the stop bar 22 and the side of the conveyor frame 2. When the stop bar 22 is not rotating, it coincides with the frame edge of the conveyor frame 2 and will not obstruct the process of the mushroom bag basket 5 entering the conveyor frame 2. The side of the conveyor frame 2 is provided with a power component to drive the stop bar 22 to rotate. A limit switch 23 electrically connected to the power component is fixed to the side wall of the receiving groove 12 by welding or bolts. When the support rod 13 rotates to the vertical position, it contacts the limit switch 23. With this structure, when the AGV body 3 drives the support rod 13 to rotate to the vertical position and contact the side wall of the receiving groove 12, the AGV vehicle... The AGV body 3 drives the conveyor frame 2 to move. At this time, the support rod 13 contacts the limit switch 23 on the side wall of the receiving groove 12, causing the power component electrically connected to it to operate and drive the stop rod 22 to rotate. This causes the stop rod 22 to rotate around the top to the side of the conveyor frame 2, blocking the mushroom bag basket 5 placed on the conveyor frame 2 and preventing the mushroom bag basket 5 from falling off the side of the conveyor frame 2 during the conveying process, thus further improving the safety of the conveying. When the AGV body 3 separates from the support rod 13, the support rod 13 resets and rotates under the action of the torsion spring 14 to separate from the limit switch 23. Then the power component electrically connected to it resets, causing the stop rod 22 to automatically reset under the action of the reset spring, releasing the obstruction of the mushroom bag basket 5, making the subsequent unloading or retrieval of the mushroom bag basket 5 more convenient.

[0037] Preferably, the power assembly includes a first telescopic rod 24, which can preferably be a pneumatic cylinder or an electric cylinder. Its main body is fixed to the side of the conveyor frame 2 by welding or bolts. The limit switch 23 is electrically connected to the first telescopic rod 24. The end of the first telescopic rod 24 is rotatably connected to a contact wheel 25 via a bearing. The contact wheel 25 makes rolling contact with the area on the stop rod 22 located between the end and the rotation position. When the first telescopic rod 24 extends, it drives the contact wheel 25 at the end to move laterally and make rolling contact with the stop rod 22, thereby driving the stop rod 22 to rotate from the edge position to the side of the conveyor frame 2, stretching the return spring between the stop rod 22 and the conveyor frame 2. When the first telescopic rod 24 retracts, the stop rod 22 automatically returns to its original rotation under the action of the return spring, making the rotation control of the stop rod 22 more convenient and accurate.

[0038] Preferably, the edges of the conveyor frame 2 and the sides of the support plate 10 are both fixed with multiple L-shaped blocks 26 by welding or bolts. The L-shaped blocks 26 form a C-shaped space with the sides of the conveyor frame 2 or the support plate 10. After the stop rod 22 rotates, it enters the C-shaped area between the side of the conveyor frame 2 and the L-shaped blocks 26 from the C-shaped opening. The setting of the L-shaped blocks 26 allows the stop rod 22 to be restricted to the side of the conveyor frame 2 before and after rotation, preventing the L-shaped blocks 26 from moving in a direction other than rotation and separating from the conveyor frame 2. This effectively blocks the mushroom bag basket 5 on the conveyor frame 2, improving the blocking effect on the mushroom bag basket 5.

[0039] Preferred, refer to Figure 8 The loading frame 6 has a drive sprocket 27 and a driven sprocket 28 symmetrically connected to its two sides via bearings. The drive sprocket 27 is driven to rotate by a motor. A drive chain 29 is provided between the drive sprocket 27 and the driven sprocket 28. Fixed blocks 30 are symmetrically fixed to the loading platform 7 by welding or bolts. The fixed blocks 30 are fixed to the drive chain 29 by welding or bolts. With this structure, when the motor drives the drive sprocket 27 to rotate, the drive chain 29 rotates with the cooperation of the driven sprocket 28, thereby driving the fixed blocks 30 and the loading platform 7 to move vertically, realizing the vertical traction and lifting of the loading platform 7, thus making the lifting and lowering control of the loading platform 7 more convenient and accurate.

[0040] Preferred, refer to Figure 9The loading platform 7 has a hidden groove 31 on its side for use with the push plate 9. The size of the hidden groove 31 is larger than that of the push plate 9, so that the push plate 9 can be hidden in the hidden groove 31. This makes it less likely for the mushroom bag basket 5 to come into contact with the push plate 9 when it is moved onto the loading platform 7, making the transfer of the mushroom bag basket 5 smoother. The push plate 9 is symmetrically fixed with guide frames 32 by welding or bolts. The guide frames 32 pass through the hidden groove 31 and are slidably connected to it. The loading frame 6 is fixed with a second telescopic rod 33 by welding or bolts. Preferably, a cylinder or electric cylinder structure can be used. The movable end of the guide frame 32 and the second telescopic rod 33 are connected by welding or bolts. When the second telescopic rod 33 moves in extension and retraction, it can drive the guide frame 32 and the push plate 9 to move laterally, so that the push plate 9 extends out of the hidden groove 31 to push the mushroom bag basket 5. The structure is simple and the pushing of the mushroom bag basket 5 is more stable and smooth.

[0041] Preferred, refer to Figure 3 and Figure 6 The bottom of the conveyor frame 2 is symmetrically fitted with side baffles 34 on both sides of the AGV body 3 by welding or bolting. The side baffles 34 restrict the relative position of the AGV body 3 and the conveyor frame 2 on the left and right sides, so that the AGV body 3 will not separate from the conveyor frame 2 when pushing the conveyor frame 2 to move left and right, making the transfer and conveying of the conveyor frame 2 more flexible. The side of the loading frame 6 is provided with a positioning plate 35. Preferably, the positioning plate 35 has an L-shaped cross-section and is fixed to the ground on the side of the loading frame 6 by welding or anchor bolts. The positioning plate 35 is in contact with at least two sides of the conveyor frame 2. This structure allows the positioning plate 35 to restrict the position of the conveyor frame 2 when it is pushed to the side of the loading frame 6 by the AGV body 3, so that the conveyor frame 2 can be aligned with the loading frame 6 more quickly and accurately, making the subsequent transfer of the mushroom bag basket 5 onto the conveyor frame 2 more efficient and accurate.

[0042] Working Principle: The structure of this invention utilizes the loading platform 7 on the loading frame 6 to transfer the mushroom bag basket 5 from the discharge roller conveyor 1 to the conveyor frame 2. As the mushroom bag basket 5 moves from the discharge roller conveyor 1 to the roller shaft 8 of the loading platform 7, the vertical sliding of the loading platform 7 aligns it with the support plates 10 at different heights on the conveyor frame 2. Simultaneously, the push plate 9 pushes the mushroom bag basket 5, allowing it to smoothly transfer from the loading platform 7 to the support plates 10 at different heights on the conveyor frame 2. This achieves rapid loading and transfer of the mushroom bag basket 5, improving the efficiency of mushroom bag transportation. Multiple [unclear - possibly referring to a specific type of equipment] are rotatably arranged at the bottom of the conveyor frame 2. A turntable 11 is provided with multiple receiving slots 12. A support rod 13 is rotatably connected to one end of the top of each receiving slot 12. A torsion spring 14 is provided between the support rod 13 and the receiving slot 12. The bottom end of the support rod 13 extends obliquely outwards to the outside of the receiving slot 12 under the action of the torsion spring 14. This allows the AGV body 3 to contact the support rod 13 when entering the bottom of the conveyor frame 2 from one side, driving the support rod 13 to rotate and enter the interior of the receiving slot 12. Similarly, when the AGV body 3 enters the bottom of the conveyor frame 2 from the other side, it contacts the support rod 13, driving the support rod 13 to rotate to the outside of the receiving slot 12, where it becomes vertical and contacts the side wall of the receiving slot 12. This structure allows the AGV body 3 to enter the bottom of the conveyor frame 2 from one side and contact the support rod 13, driving the support rod 13 to rotate to a vertical position and contact the side wall of the receiving groove 12. This allows the AGV body 3 to move smoothly by pushing the conveyor frame 2 under the connection of the support rod 13. When the entry side of the bottom of the conveyor frame 2 is blocked, the AGV body 3 can enter the bottom of the conveyor frame 2 from the other side. At this time, the AGV body 3 will contact the support rod 13 and drive the support rod 13 to rotate into the interior of the receiving groove 12. After the AGV body 3 passes the support rod 13, the support rod 13 will return to its original position and extend into the receiving groove 12 under the action of the torsion spring 14. When the AGV body 3 moves in the opposite direction, it can drive the support rod 13 to rotate to a vertical position again, so that it can be well connected and cooperate with the conveyor frame 2 in different environments. After the conveyor frame 2 moves into place, the AGV body 3 only needs to move in the opposite direction to automatically detach it from the support rod 13, so that the conveyor frame 2 can be left alone in the storage position. This makes the connection or separation of the AGV body 3 and the conveyor frame 2 more convenient, simplifies the control steps of the AGV body 3, and does not require extensive modification of the hardware and software of the AGV body 3. It only requires controlling the body to move, which greatly reduces the difficulty and cost of modification.A steering assembly is provided at the bottom of the conveyor rack 2 to drive the turntable 11 to rotate. This structure allows the AGV vehicle 3 to transport an empty conveyor rack 2 to its designated location and fill it with mushroom bag baskets 5. When it needs to be transported back to the storage location, the steering assembly drives the turntable 11 to rotate 180 degrees, allowing the support rod 13 to rotate towards the storage location. This enables the AGV vehicle 3 to move the filled conveyor rack 2 towards the storage location. Similarly, when the conveyor rack 2 needs to be transported out of the storage location, the steering assembly drives the turntable 11 to rotate 180 degrees, allowing the support rod 13 to rotate outwards from the storage location. This allows the AGV vehicle 3 to transport the transported conveyor rack 2 back out in the opposite direction. This makes the transport operation of the conveyor rack 2 more convenient and smooth, improving the ease of control over its transport.
